Title:
POLYMER ELECTROLYTE MEMBRANE, MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL
Document Type and Number:
Japanese Patent JP2012164647
Kind Code:
A
Abstract:
To provide a polymer electrolyte membrane suppressing decrease in molecular weight by deactivating radicals generated at an inside and increased in durability.
A polymer electrolyte membrane 12 includes: a membrane-like base material 12X formed of a polymer electrolyte; and metal fine particles 13A dispersed in the base material 12X. A formation material of the metal fine particles 13A includes one or more metals selected from the group consisting of noble metals and noble metal alloys, and the metal fine particles 13A are dispersed so as to have a concentration gradient in the thickness direction of the base material 12X.
